We have hence explored automatic approaches to learn the network architecture as well. Our first attempt [1]} was based upon a specific variant of differentiable architecture search [2]} known as partially-connected differentiable architecture search (PC-DARTS) [3]}. Architecture search is performed using a pair of core network components referred to as cells. Cells are defined by both architecture parameters and network parameters, both of which are jointly optimised during the first of two stages referred to as the architecture search stage.
